Depends on which Bluetooth/USB option you selected. If you went with 6NK (around £600) then you should have voice control. If you went for the cheaper option (6NH - £265 iirc) then you won't have voice control.
I went for the cheap option as I have voice control in my M3 and it's a complete pain; I almost always give up after a few minutes in frustration and end up using the idrive for the right number to call!
Hope this helps and good luck with the new car, looks great.
